6.6 UPS TEST
The UPS TEST menu allows to carry out a switching test of the inverter. The inverter is
switched off and the load is transferred to the bypass supply. The inverter supply is
automatically restored after a few seconds.
Possible loss of supply
In case of power failure while the test is being performed, the immediate operation of
the inverter is not guaranteed.
6.7 BATTERY TEST
The BATTERY TEST menu allows to carry out a short discharge test of the battery. In case
the battery is not efficient, the alarm “A10 – BATTERY FAULT” is generated at the end of the
test.
Possible loss of supply
This test can affect the continuity of supply to the loads if the battery is not fully
charged.
6.8 SYSTEM RESET
The UPS is equipped with internal protections which block the system or some of its
sections. The alarm can be cleared and normal operation can be resumed via the RESET
menu. In case the failure persists, the UPS will return to the previous failure condition.
In some cases the RESET is necessary to simply reset a failure signal, then the UPS will
resume operation.
